How do I add a new column to an existing table, and fill it with number (starting at 1) so I can use that column as the PK? Step-by-step instructions would be great, I'm having a lot of trouble with this!
View RepliesHi,
I am trying to create a primary key attribute which uses autonumber but takes its first 5 characters from another attribute in the same table and then assigns an incemental autonumber after it.
For example:
CompanyName+Autonumber
Strawberrysoup + 001 = Straw001
Does anyone have any ideas - this would be greatly appreciated.
Thanks.
Hi,
Its good to be back after a long time. Hope everyones fine.
I have a query and would appreciate any help.
I have a master-table (tblM) and two related tables (tbl1, tbl2) with one-to-one relation.
Relation1 : tblM.ID (autonumber) related to tbl1.caseID (number;LongInteger)
Relation2 : tblM.ID (autonumber) related to tbl2.caseID (number;LongInteger)
Relations are cascaded (referential integrity imposed).
I import data from excel and feed fields of tblM (I dont feed ID field from excel as it generates autonumber). At a time I feed 150 records (daily).
I have a front-end based on query from three underlying tables. Data-entry-operators do not work on tblM data as it is readonly in the front-end. They enter data in the tbl1 and tbl2 columns.
I noticed as they start entering data in tbl1 columns, the tbl1.caseID column gets data from tblM.ID on its own. Same happens in the case of tbl2.
My observation is :
I find that tblM.ID is not equal to the number of records available in tblM. (ie tblM.ID is more/less than number of records in the table. So the tblM.ID generated is not in serial.
Next time as I start importing data from excel file to tblM it gives me error and not allowing further import.
Any help!
Thanks and regards,
Prodigy.
Is there a way to add a column in a query with an autonamber
function ? What I need to achieve, is to assign a unique number to
identify each row of the query.
Why one would want a unique index on an ID key ? It can't be effectively used in joins and is never used in a where clause. So why have one ?
View 14 Replies View RelatedI've just begun using microsoft access and would like to create a primary key on a table of data that has been sorted alphabetically. However, when I try to create this key (designview -> auto number-> increment) it autonumbers for the column the way it was before i sorted it. Is there a known way of doing this?
View 7 Replies View RelatedI am using a form based on a table in MS Access 2010 for data entry.
The Data Type for column ID is AutoNumber with Increment=1. When I found ID for recent entries gets an anomaly (e.g. should be ... 3, 4, 5 ..., but it shows ... 3, 5, 6 ... that misses 4), I tried to refresh/change the ID column with the following steps:
1). Change the Data Type for column ID from AutoNumber to Number
2). Add a new column IDD and set its Data Type as AutoNumber
3). Delete the original column ID
4). Change column name IDD into column name ID
However, I got a problem with step 2): here the order # for the records becomes messed up, e.g.
Should be:
ID IDD
1 1
2 2
3 3
5 4
6 5
7 6
... ...
But, I got:
ID IDD
1 3
2 4
3 5
5 1
6 2
7 6
... ...
Why? Is this caused by the relationships between this table and other tables?
Hi all,
In the organisation that I work for employees get paid every 2 weeks on a Saturday. So for this financial year the pay period end dates have been 08/07/2006, 22/07/2006, 05/08/2006 etc
I have a column in an Access table listing various dates. I want the next column to be
populated with the next pay period end date after that date.
So if DATE is 05/07/2006 I want PAY PERIOD END to be 08/07/2006
and if DATE is 09/07/2006 I want PAY PERIOD END to be 22/07/2006 etc
How do I do this?
Kind Regards,
Matthew
Please would you be able to advise me how I would copy data from a column in one table to a column another table.
But I need to only use table not a query.
Thank you in advance for your help.
I have two tables linked to each other in one to many relationship. Instead of auto number, the date and shift (Text) is being used as the primary keys (Composite Primary Key). Here is the tables structures,
Payouts Table:
Date: Primary Key
Shift (Day or Night) : Primary Key
Bills Table:
Date: Primary Key
Shift (Day or Night): Primary Key
Autonumber: Primary Key
The tables Payouts and Bills has one to many relationship. One payout row can have many bills. The problem is that I want to start the Autonumber in bills table everyday from 1. As date and shift are different for every day so even if i start bills from 1 everyday, it wont make same primary key. I can do it manually but I want to make it automatically.
I have a table that stores orders in. There is a form to input data into this table, that I choose the products from a products table (using a subform) for the order. Once I submit the form, it submits several rows according to how many products I chose (a row for each product and the order) to the orders table.
The orders table has a autonumber primary key ID, so each of these rows has a different ID number.
I also want a column to store an order number (field: OrderNo) that is the same for each row (each product) for this order in question and not be different, allowing me to do a query for that order number and see all the products under it.
So I need the form to lookup the last highest order number from the OrderNo field, add +1 then when I add a product, it gives the SAME number to each one.
I hope this makes sense and I hope you can explain to how I do this? :)
Thanks,
Nick.
Is there a way to see what the next autonumber is in my table?
View 8 Replies View RelatedHow can I update (some columns) in a table from the same table based on a Criteria column in the same table.
View 2 Replies View RelatedI have a form, its based on a query. That query contains an Autonumber(intID) from a Table(customers). I also have another table(dealers), that uses the ID number as well. Next to the dealer info, I can click the "+" and it'll show all customers pertaining to that dealer.
I've seen some that have had different ID numbers. In the form, one has the ID of 222...while in the Dealer Table it has the ID of 227.
Does anyone know what the problem is?
Also...I have a subform where you can add a dealer to this Dealer Table if it does not exist in the combo box. Here's the code:
If MsgBox("Add New Dealer Number?", vbYesNo, "Warning") = vbYes Then
DoCmd.OpenForm "DealerContact", acNormal, , , acFormAdd, acDialog, NewData
Response = acDataErrAdded
End If
Thanks for the help.
I need to make changes to a table already containing data. Currently the autonumber field is simply there as a primary key, but I now wish to use it for another number field (Accession No) which was previously completed manually.
As this doesn't seem possible or practical (as I need the flexibility to overwrite the number sometimes), I just want the autonumber to also appear in the Accesion No field when a new record is added (but be manually overwriteable).
I've had a play with default values and lookups, but with no success, and haven't found anything on the forum. Where am I going wrong, or is this just not possible?
Thanks for your help.

I have a table named tblProjectNumber that has a autonumber field. In design view under the format property I have "NC07-"00000, this returns the a new project number with the text in front of it. What I would really want is for the text the change dynamically with the year. So an example would be NC07-00000 for project numbers created this year but I will manually have to change it for next year and the all of the previous project numbers will change accordingly. I have tried "DateSerial(Year(Date())-"00000 , Date("yy") and I can't get it tto work.Any help would be great.

Hi :)
I have solved a m:n relationship by adding a junction table. The composite primary key in the junction table is made up of primary keys from the other two tables, and both of theses primary keys are set to autonumber.
My question is this: Is it correct to set both parts f the composite key in he junction table to number rather than autonumber?
I was thinking that since autonumber should be set only once, the junction table should just take on what ever value there is in the primary keys of the other two tables.

Hi, I just a fresh user for the Microsoft Access. I have some question on the forms. I created a form and there is a field name Membership Id. In this field I created using AutoNumber format. I was requested this membership number needed to add also some Area Code and BranchCode infront of it. How could I add this into this membershipID so I could have this few info combine and shown in my form(textlabel) ? :p :p
View 1 Replies View RelatedHi,
I'm new to this forum and have a question:
I want to create a table with an Autonumber field using a SQL statement,
in Microsoft Access Database, something like this:
Cnn.execute "CREATE TABLE newtable (id Long, Name Char(100)) "
is there something to put in place of "long" to make the field autonumber?
I tried the word "autonumber", but did not work.
Many Thanx.
Hadi.
I have a table where one field needs to be an autonumber, however, that autonumber needs to be calculated. This field is not based on any other information in the database, but there's a very complicated mathematical process behind it, which I'm figuring out...I just need to know once I get that code complete, how do I tie it into the table?
View 7 Replies View RelatedI have a table that has a primary key that does an autonumber in increments. Then I made some queries that will append records by date and then also another query that will delete what was appended. Then I created a reverse sequence of this process in case I change my mind and would like to put back the records I archived, however, when I do this, the primary key is now thrown off and will still revert to the last primary key that was appended before the archive ever took place. In other words it still thinks that the records I appended before I did the reverse, are still there. So now it will not let me save the record because it is a duplicate.
Is there a way to set the autonumber for the primary key to where I want it to begin?
I have the field called subject_id which is autonumber in the form of 10001,10002,... And I want the field with the same format to appear in another table. But appending it leads to different numbering, i.e. the filed becomes 1, 2, ... instead of 10001, 10002 as I've formatted it in its original table. How could I append/copy such a field?

Hello,
I'm making a MS Access frontend for some tables on the Oracle 8 database at work. The tables are linked ofcourse.
One table has an AUTONUMBER field on the Oracle and it seems to give me trouble to insert new records.
When I try to insert a new record (leave the autonumber field blank) I get the following error: "ODBC — insert on a linked table <table> failed. (Error 3155)" followed by the error "[Microsoft][ODBC Driver for Oracle][Oracle]ORA-01722: invalid number (#1722)".
When I look at the Oracle documentation I got this:
ORA-01722 invalid number
Cause: The attempted conversion of a character string to a number failed
because the character string was not a valid numeric literal. Only numeric fields or character fields containing numeric data may be used in arithmetic functions or expressions. Only numeric fields may be added to or subtracted from dates.
Action: Check the character strings in the function or expression. Check that
they contain only numbers, a sign, a decimal point, and the character "E" or "e" and retry the operation.
I checked the INSERT statement: "INSERT INTO AFM_HV_PROP_VALUE (HV_INST_ID, HV_PROPERTY_ID, TABLE_NAME, HV_PROPERTY_VALUE) VALUES (4, 'V_TESTJE', 'hv_inst', '123465')" and everything seems to be allright. The value that's causing the error is the "4" that gets in the "HV_INST_ID"-field.
Using TOAD to execute the SQL Statement, there is no problem at all.
When I look at the table design in MS Access I see that the Autonumber field is of the type "Double". That doesn't seem right to me...
Anyone some suggestions? I'm running out of courage :s

Hi All,
I am trying to create a make-table query, with a new AutoNumber field.
I know that if you are creating a new Text field you type FieldName: "" in Field and for a Number field you would type FieldName: [], but what do you type for an AutoNumber field?
